proper check of Proof.is_relevant (again, cf. c3e99efacb67 and df8fc0567a3d);

support nested Thy_Syntax.element; more explicit Keyword.is_proof_body; tuned;

back to non-schematic 'sublocale' and 'interpretation' (despite df8fc0567a3d) for more potential parallelism;

help JVM to cope with large symbolic structures;

improved scheduling of forked proofs, based on elapsed time estimate (from last run via session log file);

read logs from failed sessions as well; proper output base directory (which is two steps upwards);

recover timing information from old log files; use session timing for queue ordering; pass command timings to ML process (still unused);

suppress timing message in full PIDE protocol -- this is for batch build;

support for build passing timings from Scala to ML;

support for prescient timing information within command transactions;

emit command_timing properties into build log; tuned;

generate Isar proof if Metis appears to be too slow

swap slices so that the last slice is more complete (for minimization)

tuning

ensure all conjecture clauses are in the graph -- to prevent exceptions later

generalize syntax of SPASS proofs

tweaked hack some more

more simplifying constructors

remove needless steps from refutation graph -- these confuse the proof redirection algorithm (and are needless)

more precise error

improved hack

upgraded to Alt-Ergo 0.95

don't pass chained facts directly to SMT solvers -- this breaks various invariants and is never necessary

trust preplayed proof in Mirabelle

added case taken out by mistake

tuning (removed redundant datatype)

minimize SMT proofs with E if Isar proofs are desired and Metis managed to preplay

honor linearization option also in the evaluation driver

got rid of rump support for Vampire definitions

optimize Isar output some more

turn off more evil Vampire options to facilitate Isar proof generation

fixed typo in option name

tuning

use new skolemizer only if some skolems have two or more arguments -- otherwise the old skolemizer cannot get the arg order wrong

slacker comparison for Skolems, to avoid trivial equations

auto-minimizer should respect "isar_proofs = true"

made "isar_proofs" a 3-way option, to provide a way to totally disable isar_proofs if desired

alias for people like me

dropped spurious left-over from 0a2371e7ced3

avoid using "smt" for minimization -- better use the prover itself, since then Sledgehammer gets to try metis again and gives the opportunity to output an Isar proof -- and show Isar proof as fallback for SMT proofs

interpret "max_facts" argument in a slice-dependent fashion, instead of forcing the same number of facts to all slices

delete also predicates on relations when hiding an implementation of an abstract type

reintroduced crucial sorting accidentally lost in 962190eab40d

compile

provide two modes for MaSh driver: linearized or real visibility

implement (more) accurate computation of parents

tuning

split isar_step into isar_step, fix, assms; made isar_proof explicit; register fixed variables in ctxt and auto_fix terms to avoid superfluous annotations

simplified byline, isar_qualifier

tuned code: factored out parent computation

tuned code

simplify definition as sort constraints ensure finiteness (thanks to Jesus Aransay)

fundamentals about discrete logarithm and square root

Sieve of Eratosthenes

note on parallel computation

corrected and clarified Code_Binary_Nat vs. Code_Target_Nat

simplified construction of upto_aux

merged

restored proper order of NEWS entries (lost due too long-waiting patches)
